Book Description
This report presents cost and productivity results, as well as results about the harvesting-related damage incurred by the understory in a mixedwood harvesting trial. The trial compared conventional and Scandinavian harvesting equipment, levels of operational supervision, and special operational techniques. The study took place in the northern boreal forest region of Central Alberta during 1988 to 1990. Recommendations are proposed to guide operators, planners, supervisors, and regulators when they harvest 2-storied mixedwood stands and want to protect a significant portion of the understory.

Book Description
This project was aimed primarily at technology tranfer, demonstrating the integration of silvicultural and harvesting techniques for protecting spruce understories in mixedwoods. This report provides details of the silvicultural component. It stresses post-harvest implications, particularly blowdown risk and growth and yield potential of released understory, and regeneration and growth of spruce, aspen, and poplar on mechanically harvested mixedwood sites. The project addresses concerns about maintaining the coniferous component of mixedwood forests and finding alternatives to clearcutting. It covers the current status of operational understory protection and some related aspects of integrated resource management.

Book Description
This report reviews the nature of wind damage in forest stands and relates that damage to the silvicultural systems used or being developed for management of boreal mixedwoods. The report gives detailed consideration to the approaches for minimizing wind damage in released white spruce understory specific to the two-stage harvesting and silvicultural system. The review addresses the individual tree stability, stand stability, and external stability factors such as site characteristics, topography, windiness of the region, and sheltering effects of adjacent stands, and relates these to a framework for recognizing high-risk sites and stands. The report also discusses principles of wind damage management in the context of designing silvicultural systems with incremental wind protection levels.

Book Description
Presents proceedings of a workshop held to summarise the current state of knowledge about the ecology of boreal mixedwood forests, to discuss management philosophies for these cover types, and to present information on new research relevant to the future management of boreal mixedwoods. Topics of individual presentations include boreal forests in Ontario, the role of forest disturbance, forest management, industrial use of boreal mixedwoods, forest data bases, forest vertebrate communities, habitat quality indicators, forest microclimate, organic and nutrient removals associated with harvesting, climate change impacts, prescribed fire, silvicultural operations, harvesting methods, vegetation control, ecosystem response to disturbance, site preparation, and effects of harvesting on forest fauna.

Book Description
This volume presents papers given at a workshop held to review current knowledge of the silviculture of temperate and boreal broadleaf-conifer mixtures and the consequences of growing mixed stands. Topics of the papers include the importance of mixedwood stands, managing birch-dominated mixed stands, competition dynamics, silvicultural systems, stand dynamics, vegetation management, red alder-conifer stands, mixedwood management research, white spruce and aspen stands, vertical stratification in mixed-species stands, habitat management for game and parasite control, simulation of long-term impacts of alder/fir mixtures, understory protection, fertilisation, control of spruce weevils, and litter decomposition.

Book Description
Boreal mixedwood sites, an ecologically & economically valuable component of Ontario's forested landscape, are typically dominated by hardwoods soon after major disturbances such as clear-cutting. Alternative harvesting methods may help reduce the level of competition in the regeneration environment and enrich the conifer content. This report describes field trials in northern Ontario that tested approaches for maintaining or increasing the conifer component in hardwood-dominated stands. The report explains the context & rationale for the trials; documents the locations, designs, layouts, & methods to facilitate reassessment over the long term; and presents responses observed during the first three years of treatment.
